(5) _Lessons._ There should be graded lessons for each department. If a graded system be followed in the school, as it should be, with different subjects, text-books, and lessons for each department, giving to the entire school a regular, systematic, progressive curriculum, this requisite will be met. If, however, the uniform lesson for all the school be followed, as at present is still the case in many Sunday schools, the graded teaching must be given in the form of supplemental lessons, taught by the head of the department where it has a separate room, or by the teacher if the departments must be assembled in one room. In some form the graded teaching is an absolutely essential requisite of the graded school. Most schools, when once thoroughly graded, will realize the need of the next step in the evolution of the institution--lessons graded in subjects as well as in methods for the several departments. (6) _Basis of Promotion._ The question is often asked, "Should promotions be made on the basis of age, or as the result of examinations?" The examination system may be regarded as desirable in the Sunday school, but there are as yet few schools where thorough examinations can be rigidly insisted on as a part of the school system, and promotions invariably made to depend upon standing. A school which meets only once a week, for a session of less than an hour and a half, and with but one lesson period of forty minutes or even less, cannot maintain the same strictness in its standards as the public school. Moreover, new scholars are continually entering the schools, and, while most of them begin at the foot of the ladder in the Primary Department, yet others enter at various ages and in various grades. Any system of promotion based merely upon acquirement attested by examination is sure to become in many instances a meaningless form when applied to the Sunday school. Yet acquirements and examinations need not be ignored in the graded Sunday school. There may be certain ages at which the pupils shall by right pass from a lower grade to a higher. But it may also be arranged that pupils who are exceptionally bright, well-informed, and studious can be promoted a year in advance of their classmates by passing examination. Let the examination be given in writing to all the pupils, and let all be urged to take it; with the promise that those who pass will be promoted, even though they be less than the required age. But let it also be understood that failure to pass the examination will not keep the student for more than one year from promotion. In other words, the examination may well be made the door through which earnest students may pass on, and so keep abreast of their equals in training and ability.
